Ja'far ibn Muhammad al-Sadiq (Arabic: جَعْفَر بْن مُحَمَّد ٱلصَّادِق, romanized: Jaʿfar ibn Muḥammad al-Ṣādiq; c. 702–765 CE) was a Muslim hadith transmitter and the last agreed-upon Shia Imam between the Twelvers and Isma'ilis. Known by the title al-Sadiq ("The Truthful"), Ja'far was the eponymous founder of the Ja'fari school of Islamic jurisprudence. In the canonical Twelver hadith collections, more traditions are cited from Ja'far than that of the other Imams combined, although their attribution to him is questionable, making it hard to determine his actual teachings. Among the theological contributions ascribed to him are the doctrine of nass (divinely inspired designation of each Imam by the previous Imam) and isma (the infallibility of the Imams), as well as that of taqiya (religious dissimulation under persecution). Al-Sadiq is also revered by Sunni Muslims as a reliable transmitter of hadith, and a teacher to the Sunni scholars Abu Hanifa and Malik ibn Anas, the namesakes of the Hanafi and Maliki schools of jurisprudence. Al-Sadiq also figures prominently in the initiatic chains of many Sufi orders. A wide range of religious and scientific works were attributed to him, though no works penned by al-Sadiq remain extant. Ja'far al-Sadiq was born around 700 CE, perhaps in 702. He was about thirty-seven when his father, Muḥammad al-Bāqir, died after designating him as the next Imam. As the sixth Shia Imam, al-Sadiq kept aloof from the political conflicts that embroiled the region, evading the requests for support that he received from rebels. He was the victim of some harassment by the Abbasid caliphs and was eventually, according to Shia sources, poisoned at the instigation of the caliph al-Mansur. The question of succession after al-Sadiq's death divided the early Shīʿa community. Some considered the next Imam to be his eldest son, Isma'il al-Mubarak, who had predeceased his father. Others accepted the Imamate of his younger son and brother of Isma'il, Musa al-Kazim. The first group became known as the Isma'ili, whereas the second and larger group was named Jaʽfari or the Twelvers.
